[Q] Speakerphone Echo / Scraping Sound
With my Thunderbolt, the other callers hear a constant echo of their own voice, combined with a constant scraping sound. It sounds like half-duplex, but with constant echoes and horrible sounds. It is nearly impossible to hold a comfortable conversation with the party using the Thunderbolt, but calls sound fine to the person using the device.
Anybody else running into this problem, or found a fix? Haven't monkeyed around with the phone, and read that some people had better luck in just exchanging the phone.
I should mention: the scraping sound is incredibly
loud. It's like the sound of someone scraping ice from a windshield, or pushing a giant cabinet along a concrete sidewalk.
